Products Description
WCu alloy is the composite of Tungsten and Copper, which own the excellent performances of Tungsten and Copper, such as heat-resistant, ablate-resistant, high-intensity, excellent thermal and electrical conductivity. WCu alloy is easy to be machined. WCu alloy is used widely in such industries as engine, electrical power, electron, metallurgy, spaceflight and aviation. Using CIP formation, sintered tungsten skeleton and infiltrating copper (silver) technology, large size and special shape products of WCu composites with 6-90 percent of copper are produced, such as electric contacts, electrode, refractory parts, heat sinks and parts of rocket, We can also produce WCu alloy sheet material, tubing, plate and other small products by mould pressing, extrusion pressing and MIM.
WCu Alloy applications: For the spark erosion of dies of cemented carbide and for making high speed steel and switches and contacts in high and low voltage electrical devices.
Features
Excellent thermal properties: WCu alloy has a high melting point, high thermal conductivity, and low thermal expansion. Copper provides high thermal conductivity, while tungsten gives low thermal expansion, so it performs well in high-temperature environments.
Good electrical properties: This alloy has high electrical conductivity, which increases with more copper content. It also resists arc erosion well, making it suitable for high-voltage and high-current conditions.
High strength and wear resistance: Tungsten's hardness and strength give the alloy good wear and abrasion resistance, so it works well under high stress and friction.
Easy to process: Even though the alloy contains hard tungsten particles, it can still be machined easily using standard methods.
Applications
Aerospace Industry: WCu alloy is widely used in rocket nozzle linings, tail fins, and other high-temperature parts because it has high thermal conductivity, low thermal expansion, and good resistance to heat damage.
Electronics Industry: In electronic packaging, WCu alloy is used for chip carriers, substrates, flanges, and frames. Its thermal expansion matches well with semiconductor materials like silicon and gallium arsenide.
Power Industry: WCu alloy is used to make electrical contacts in high and medium-voltage equipment, such as circuit breakers, contactors, and transformer tap changers. It is also used for electrodes in EDM (electrical discharge machining) and electrochemical machining.
Machinery Manufacturing: WCu alloy can be used to make high-temperature molds and resistance welding electrodes. Its wear resistance and heat resistance make it perform well in these applications.

FAQ
Are you a factory or manufacturer?
A: Yes, we are a factory but generally, we use our trading company to handle the business abroad. It will be convenient to receive the remittance and arrange the shipment.
What is the delivery method?
A: Generally, we send cargo by UPS, DHL or FedEx. Also, we can send by sea to seaport or by air to the closest airport.
Why is your product so cost-effective?
A: We cut out the middlemen in the end-to-end manufacturing process. Rather than obtaining semi-finished goods from other suppliers, we obtain our raw material of APT powder directly from its source.
Do you do spot quality inspection or full inspection?
A: 100% full inspection. Inspectors will check the finished product individually, to ensure they adhere to all parameters. All unqualified products are discarded.
How do you ensure your lead time?
A: We have an efficient Order Management System, from material preparation to machining, and finally to a full inspection. Every stage of production is strictly monitored and controlled to give you an accurate delivery time.
What is the MOQ of WCu Tungsten Copper Alloy Bar?
A: Depends on quantity, generally, no MOQ limit.
How to pay for it?
A: A bank transfer (T/T) will be acceptable.
What is the delivery time?
A: around 7-20 days which depends on the quantity and production.
What is kind of the package?
A: Generally, we use a carton case or plywood case with protective material inside to ensure the save of cargo
What is the lead time?
A: from order placed to cargo receiving will take around 10-25 days.
What is WCu alloy?
WCu alloy is a composite material made of tungsten (W) and copper (Cu). It combines the high melting point and strength of tungsten with the excellent thermal and electrical conductivity of copper.
What are the main properties of WCu alloy?
High thermal conductivity (good heat dissipation)
Low thermal expansion (stable at high temperatures)
High electrical conductivity (good for electrical applications)
Strong and wear-resistant (durable under stress)
Good arc resistance (prevents damage in high-voltage conditions)
Why is WCu alloy good for high-temperature applications?
Because tungsten has a very high melting point, and copper helps conduct heat away quickly, preventing overheating.
Can WCu alloy be machined easily?
Yes, despite containing hard tungsten, it can be processed using standard machining methods.
How does copper content affect WCu alloy?
More copper improves electrical and thermal conductivity but may reduce strength. The ratio is adjusted based on the application.
Is WCu alloy corrosion-resistant?
It has good resistance to heat and wear, but copper can oxidize over time. Protective coatings are sometimes used.
Is WCu alloy expensive?
Yes, because tungsten is a rare and costly material. However, its performance justifies the cost in critical applications.
